I have read that the FASS fuel pump will not work with a certain lift pump that many Chrysler dealerships installed after the stock one failed. Was the stock one in the tank on a 2003? Or was it up by the fuel filter? I know the one that is currently on my truck is in the tank. I just need to know how to tell if it is one that will work with the FASS or the Fuel Boss.

Thanks

I'm not quite sure if I completely understand your question, but if you are asking if a FASS will work with an in tank fuel pump the answer is YES. You'll need to by-pass the pump and install a draw straw in your tank. Nothing to it.
